I've done several custom hack's for customers based on the wu-ftpd and
effectivly chroot() the user to his section. 

The backends we used withere either berkely DB (shared with apache and
mod_rewrite), Netscape's LDAP and, in one case, mSQL. But in all of the
cases, generalizing made little sense, as it was simpler to just cook a
custom hack for a specific case. We are only talking a couple of lines of

Note that we had a _much_ harder time getting the ftpD to scale in the
rigth sort of way, and make sure we had some level of indirection when
'routing' a user to the right ftp server.

One important hack was to 'trap' some of the ls and other command possible
and not rely on a group/passwd and so on for the translation but issue the
native one.
